ESR Dosimetric Properties of Sodium Glutamate

Document Type : Original Article

Abstract

 MONO SODIUM GLUTAMATE powder and rods (3x 10 mm) were studied to be a radiation sensitive material for ESR dosimetry. Samples were irradiated with 60Co γ- rays. The developed signal after irradiation increases with the increase of the mono sodium glutamate in the rods. The prepared powder can be used in the dose range from (10-90) kGy, whereas the rods are useful in the range from (10-120) kGy. The obtained number of free radicals per 100ev (G value) was found to be 0.201± 0.01. The g factor is 2.0113± 0.0001. The rods have the advantage of negligible humidity effects during irradiation. The pre and post irradiation stability was found to be satisfactory.
